  • Patent number: 10681912
    Abstract: A dispersion solution containing ultrafine metal particles, comprising a low-boiling solvent and, contained therein, ultrafine metal particles of any one of Ag, Cu or Zn having a fatty acid and a glyceride coordinated on the surfaces thereof. The dispersion solution contains, dispersed therein, ultrafine metal particles that have excellent antibacterial power at a high concentration without being aggregated. The dispersion solution maintains excellent dispersion property even after the passage of long periods of time and also exhibits very high degree of transparency even when it is mixed into a resin composition.

  • Patent number: 8232493
    Abstract: An operating device is provided having a supporting member, a button, an elastic member, and a bearing member. The supporting member has an opening which passes through the thickness direction of the supporting member. The button has a shaft and an engaging portion. The shaft is arranged such that the axial direction of the shaft is parallel to the thickness direction of the supporting member. The engaging portion projects parallel to the axial direction of the shaft. The elastic member is set onto the supporting member so as to cover the opening, and has a projecting portion which engages the end of the shaft. The bearing member is provided between the supporting member and the elastic member, which is provided around the opening and is located nearer to the shaft than the engaging portion in the direction orthogonal to the projecting direction of the shaft.
